This simple pressure relief valve used to control and limit the pressure build-up in a system. This is how it works: if pressure exceeds the amount allowed by the valve, the pressure relief valve will automatically open and release air until the pressure is reduced. Relief pressure preset to 50 psi with flow rate of 53 CFM.
